  • Rendering sub tools on vertical toolbar

    - by user146780
    I was wondering how ex Photoshop and Expression Design render sub tools. These show up when for example you hold your mouse down on the fill tool, a sub menu comes up to your right with the fill and gradient tools. I'm just not sure how to go about this because this sub menu would essentially have to be an extension of my toolbar, but then it would find itself on my Frame control. How is this handled? Would it be a good idea to just paint on my frame?

  • How should 4 decimals places behave, being simple yet powerful

    - by vener
    I have a UI question that troubled me on the best method to handle 4 decimal places for prices. In an table already cramped full of data, I would want to simplified the interface to make it not so cluttered. The actual current UI is shown below. http://i41.tinypic.com/bg5tub.jpg The problem is, for a unit price/units/D.Price and Dis.(Discount) to have 4 decimal places ($0.3459) is quite rare but it still happens (5 in 100 entries). This will result a lot of junk decimal places, cluttering up the interface. What is the best solution to this problem? In short, I want to declutter it yet maintain the precision. Note: This is web app

  • Refactoring FAT client legacy application

    - by Paul
    I am working on a fat client legacy C++ application which has a lot of business logic mixed in with the presentation side of things. I want to clean things out and refactor the code out completely, so there is a clear seperation of concerns. I am looking at MVC or some other suitable design pattern in order to achieve this. I would like to get recommendations from people who have walked this road before - Do I use MVP or MVC (or another pattern)? What is/are the best practices for undertaking something like this (i.e. useful steps/checks) ?

  • creating a static vb.net "app" that consist of a single picture

    - by michael
    I need to create a vb.net program that consists of a unmovable, always on top bitmap, with no menu bar or anything, and does not show up in the task bar as program. It needs to always start in the same place. Essentially I need to mask a part of the screen by using a bitmap that blends into the scenery. I am not sure which properties I need to tweak to achieve all of this.

  • How to disable current page links in ASP.NET MVC?

    - by rem
    I'm investigating ASP.NET MVC now and noticed that in ASP.NET MVC application, which is created by Visual Studio by default, links "Home" and "About" are staying active when the user is on "Home" and "About" page correspondingly, and after clicking on the current page link page is reloading itself. What is the correct approach to disable link which points to the page, a user is already on? How to do it without violating ASP.NET MVC approach?

  • Can a thread call wait() on two locks at once in Java (6)

    - by Dr. Monkey
    I've just been messing around with threads in Java to get my head around them (it seems like the best way to do so) and now understand what's going on with synchronize, wait() and notify(). I'm curious about whether there's a way to wait() on two resources at once. I think the following won't quite do what I'm thinking of: synchronized(token1) { synchronized(token2) { token1.wait(); token2.wait(); //won't run until token1 is returned System.out.println("I got both tokens back"); } } In this (very contrived) case token2 will be held until token1 is returned, then token1 will be held until token2 is returned. The goal is to release both token1 and token2, then resume when both are available (note that moving the token1.wait() outside the inner synchronized loop is not what I'm getting at). A loop checking whether both are available might be more appropriate to achieve this behaviour (would this be getting near the idea of double-check locking?), but would use up extra resources - I'm not after a definitive solution since this is just to satisfy my curiosity.

  • How do I make dynamic windows in Swing?

    - by Roman
    I have a general question. I would like to have a window containing some buttons, radio buttons, text fields and so on. So, user can do something (write text, select options and press buttons). As the result of the user activity window should change it structure/appearance some element should disappear and some appear. How do I program such "updates"? Should I close an old window and open a new one or I can modify content of window without closing it?

  • Put `stdout` in an `NSTextView` while running the a command

    - by Koning Baard XIV
    I'm creating a Cocoa Application, which will need to run the rails command. This command generates an output, and streams it to stdout. I want to show this output to the user in an NSTextView (so basicly stream the stdout to the NSTextView). I don't really care about how I should run the command, as long as I can set the working directory. Can anyone help me? Thanks

  • UI: where to display a status result from a drag & drop?

    - by Jason S
    So I've got drag & drop working. When a drop occurs, I do some processing, and sometimes there is a result that I want to make the user aware of. Right now I am just outputting to the console which isn't very nice. What's an appropriate way to display a status result from a drag & drop? Somehow a modal dialog box seems inappropriate, and a status bar is too space-constrained, I think.

  • How to schedule heavy work for later display for Listviews?

    - by Pentium10
    I have a listview with 200 items. I use a custom view for each row. There is a code that takes some time to calculate, and because of this the list hangs out on scrolling and loads in slow (2-3sec). I have subclassed SimpleCursorAdapter, and using Filterable and SectionIndexer. I have in mind to show initially the name of the record, and put in a thread the calculation, and will show up later when it's done. How do I push back some work, and later update the listview to include the calculated data? This should show up on fly without user interaction.

  • Creating Java Dialogs

    - by mike_hornbeck
    What would be the easiest way for creating a dialog: - in one window I'm giving data for envelope addressing, also set font type from list of sizes - when clicked OK, in the same window or in next window I get preview of how the envelope would look like with the given names, and used selected font size It should look similarly to this : Should I use Jdialog ? Or will JOptionPane will be enough ? The next step will be to choose color of font and background so I must keep that in mind.

  • Why thread started by ScheduledExecutorService.schedule() never quits?

    - by moonese
    If I create a scheduled task by calling ScheduledExecutorService.schedule(), it never quits after execution, is it a JDK bug, or I just miss something? note: doSomething() is empty method below. public static void doSomething() { } public static void main(String[] args) { ScheduledFuture scheduleFuture = Executors.newSingleThreadScheduledExecutor().schedule(new Callable() { public Void call() { try { doSomething(); } catch (Exception e) { e.printStackTrace(); } return null; } }, 1, TimeUnit.SECONDS); }

  • Java swing center JDialog over parent

    - by Chris Drappier
    I have a Java swing application with a button that produces a popup window when a certain action is performed. I'd like to align the center point of the popup window with the center point of the parent window when it is rendered. How can I calculate the x,y coordinates to plug into setLocation() for the popup window? EDIT: just to clarify. I do not want the behavior of setLocationRelativeTo() because that sets the top-left pixel of the popup over the center pixel of the parent frame. I want to set the center pixel of the popup over the center pixel of the parent frame. Also, I'm not interested in whether or not a popup window is good practice. I'm past that now. thanks

  • How to use `wx.ProgressDialog` with my own method?

    - by user1401950
    How can I use the wx.ProgressDialog to time my method called imgSearch? The imgSearch method finds image files on the user's pc. How can I make the wx.ProgressDialog run while imgSearch is still running and display how long the imgSearch is taking? Here's my code: def onFind (self,event)# triggered by a button click max = 80 dlg = wx.ProgressDialog("Progress dialog example","An informative message",parent=self, style = wx.PD_CAN_ABORT| wx.PD_APP_MODAL| wx.PD_ELAPSED_TIME| wx.PD_REMAINING_TIME) keepGoing = True count = 0 imageExtentions = ['*.jpg', '*.jpeg', '*.png', '*.tif', '*.tiff'] selectedDir = 'C:\\' imgSearch.findImages(imageExtentions, selectedDir)# my method while keepGoing and count < max: count += 1 wx.MilliSleep(250) if count >= max / 2: (keepGoing, skip) = dlg.Update(count, "Half-time!") else: (keepGoing, skip) = dlg.Update(count) dlg.Destroy()

  • Placing elements (panels) within a wx.GridBagSizer

    - by JHarris
    I'm using a gridbagsizer to place two panels within a frame. control_panel = wx.Panel(self, id=ID_CONTROL_PANEL) main_panel = wx.Panel(self, id=ID_MAIN_PANEL) frame_sizer = wx.GridBagSizer(1, 1) frame_sizer.Add(control_panel, (0, 0), (2, 5), flag=wx.EXPAND) frame_sizer.Add(main_panel, (2, 0), (5, 5), flag=wx.EXPAND) frame_sizer.AddGrowableRow(0) frame_sizer.AddGrowableCol(0) self.SetSizer(frame_sizer) I want the control_panel to be above the main_panel (as you can see above). However this is the output I get: I don't know why the top panel is so much larger than the bottom panel, when I've specified the opposite. (2, 5) for the top and (5, 5) for the bottom. It also has a strange behaviour when I resize it smaller, it basically gives me what I want (see image below), but I don't know how to maintain the ratio when I make it larger again. However when you start resizing larger (even by a small amount) you can see (below) the shapes and ratio change dramatically in the other direction (with the bottom becoming much smaller and the top much larger). Still trying to learn this sizers and can't really find this problem with any of the examples I've seen. Also tried experimenting with all the parameters and doing some tests and I can't figure out what's going on here. Any help would be much appreciated.

  • J2ME linking interfaces.

    - by user554031
    Hey guys, I've been working with J2ME for a short while, however I've been unable to find anything regarding my query. I'm wanting to link interfaces, I.E A to B to C. Similar to a card layout. Information on each interface changes based on the choices the user made previously. For example City - Cinema - Cinema Listings. The eventual target is to create a MIDlet that displays information from a database (I understand a midlet needs to connect to a servlet which connects to the DB). Thanks in advance for you're time.
